The option -f is used to provide a file name when Athena is started. Once loaded, you can open a prompt (-i) and/or evaluate a Smalltalk expression (-e).

The syntax of SmallWorld has to be used for scripts. The scripts folder contains few examples. Assuming you have a scripts folder that contains the HelloWorld.st file, you can launch the shell with the following invocation:java -cp athena-0.1.jar athena.engine.AthenaShell -f scripts/HelloWorld.st -e "System println: FooClass new helloWorld"
